  • Reorder the steps in the process of longshore drift:
    Reorder the steps in the process of longshore drift:
    • 1
      Waves hit the shore at an angle due to the wind direction.
    • 2
      Sediment is moved along the beach by the swash (up the shore).
    • 3
      The backwash pulls sediment straight back down the beach.
    • 4
      Sediment moves along the shore in a zig-zag pattern over time.
    • 5
      Over time, sediment is transported down the coastline.
